  Measure 
  strata 
  without 
  meeting 
  more 
  than 
  one 
  well 
  defined 
  seam 
  

   of 
  coal, 
  and 
  it 
  seems 
  quite 
  probable 
  that 
  some 
  of 
  the 
  beds 
  reported 
  

   as 
  black 
  slate 
  may 
  also 
  represent 
  the 
  horizon 
  of 
  thin 
  beds 
  of 
  coal, 
  

   the 
  material 
  being 
  so 
  mixed 
  with 
  the 
  slate 
  as 
  to 
  prevent 
  identifica- 
  

   tion. 
  

  

  Since 
  the 
  publication 
  of 
  volume 
  6, 
  of 
  these 
  Eeports, 
  a 
  shaft 
  has 
  

   been 
  sunk 
  at 
  Sandoval, 
  reaching 
  a 
  thick 
  bed 
  of 
  coal 
  at 
  the 
  depth 
  

   of 
  C02|-

  At 
  Breese, 
  twenty-two 
  miles 
  west 
  of 
  Sandoval, 
  the 
  coal 
  was 
  found 
  

   at 
  the 
  depth 
  of 
  397^ 
  feet, 
  but 
  no 
  detailed 
  record 
  of 
  the 
  beds 
  passed 
  

   through 
  was 
  kept. 
  The 
  coal 
  ranges 
  from 
  seven 
  to 
  eight 
  feet 
  in 
  

   thickness, 
  and 
  has 
  a 
  clay 
  parting 
  an 
  inch 
  or 
  two 
  thick, 
  about 
  two 
  

   feet 
  from 
  the 
  bottom. 
  A 
  bed 
  of 
  light 
  gray 
  limestone, 
  ten 
  feet 
  in 
  

   thickness, 
  was 
  passed 
  through 
  some 
  twenty-five 
  to 
  thirty 
  feet 
  above 
  

   the 
  coal. 
  The 
  roof 
  consists 
  of 
  bituminous 
  shale, 
  containing 
  Discina 
  

   nitida 
  and 
  the 
  spines 
  and 
  dermal 
  plates 
  of 
  fishes. 
  The 
  coal 
  is 
  con- 
  

   siderably 
  impregnated 
  with 
  the 
  bi-sulphuret 
  of 
  iron, 
  and 
  is 
  gener-
